Purpose and function in the vehicle

The presented throttle pedal assembly belongs to the Pedals, pedal pads, and footrests group and is responsible for the electronic transmission of the torque request signal to the engine control unit. The “fly-by-wire” design eliminates the throttle cable, and the pedal position is read by electronic sensors, which allows for precise control of the engine’s operation and integration with electronic stability and traction control systems.

Construction and technical properties

The electronic throttle pedal for Audi is designed as a complete, permanently mounted electronic throttle pedal unit. The pedal mechanism, position sensors, and connector for the vehicle’s electrical harness are integrated into a single housing. This design facilitates service replacement – the entire assembly is removed and installed without the need for adjustment or calibration of mechanical components.

The solution used in the Audi RS4 B7 ensures:

• stable pedal position reading across the full range of travel,
• repeatable signal characteristics for the engine control unit,
• cooperation with factory safety and driving comfort systems as designed by the manufacturer.

Benefits of using the original throttle pedal assembly

Using the original throttle pedal assembly in the Audi RS4 B7 allows for maintaining the factory performance parameters of the drivetrain. Properly matched pedal characteristics translate into a predictable vehicle response to throttle input, which is particularly important in a high-performance car. The original design reduces the risk of engine control unit errors related to incorrect signals from the pedal position sensor.

This component is a beneficial choice in situations such as:

• repairing a failed pedal position sensor,
• clearing errors related to an incorrect throttle pedal signal,
• restoring the stock configuration after previous modifications.

Condition, installation, and service application

The offered assembly belongs to the group of used parts, which allows for an economical repair while maintaining the manufacturer’s original design. Before installation, it is recommended to perform a standard inspection of the electrical connector and the correctness of the mounting in the vehicle, in accordance with the Audi service procedure. Replacing the complete throttle pedal assembly is usually a straightforward task for a workshop experienced with vehicles of this brand.
